"Officers responded to Papa John's and got the information and went over to an address on MacBrae Court just a short distance away," said Klain.

Police said officers went to the address where the woman asked for delivery, carrying two empty pizza boxes. Officers said when they found the 23-year-old in the home, she allowed them to search her purse.

"When they did get into the purse, they located credit cards, probably in excess of 50 numbers, names, addresses, phone numbers, credit card numbers and security numbers needed to use the cards," said Klain.

Klain said Hildalgo recently returned to Louisville after two years in Florida, and it's believed she obtained the information from contacts in Miami, which is why the Secret Service is involved.
